Putting STLs at the ground level can help...but at some point you're just trying to fix a problem that you're purposely introducing yourself. Isn't it better to just not introduce that problem in the first place? Tie to the trees.
Now that said, and since I like to tinker, I might have a way to keep the tarp from sagging when I get into the hammock. I don't think it'll be quite as tight as tying it to the trees, but it might be just enough to convince me to take it on summer trips. It'll take a lot of words to explain, so I'll just wait until I can post some pics.
If you ever figure out a good method, it will be worth while even if not quite as tight as tied to the trees. Because in my experience so far, coverage with a minimal non-rectangular tarp is so much more effective when you don't sag far away from the tarp RL. Which is the one advantage ( other than some convenience) of a tarp attached to the hammock.
Of course, with bigger and rectangular tarps, it's all moot anyway. Because you still have plenty of coverage when tied to the trees, even after normal hammock downward sag.
